CORPORATION OF DELAWARE BOOSTER-Moron SUPPORT Application ned January 1e, 192s. serial No. 247,154.

My invention relates to railway rolling stock and consists in a novel support for a booster motor.

The term, booster motor, as will be readily understood by those skilled in the art, is applied to a motor operatively connected to a normally non-driving axle and intended to be used under abnormal conditions such as when the locomotive is starting or is laboring up a steep grade. The motor projects horizontally from the axle to which it is attached and the projecting portion of the motor is supported on a truck or from the main frame work of the locomotive. This support has previously taken the form of a spherical bearing beneath the longitudinal center line of the locomotive, which bearing has permitted the motor to tilt and turn relative to the truck or frame work according to the movements ofthe axle to which it is attached.

The main object of my invention is to provide a booster motor support which mav be applied to the motor at the sides thereof and, preferably, may support the motor throughout its width and, at the same time, permit the motor to move with the axle to which it is attached.

An additional object of my invention is to equalize the weight of t-he motor, when the latter is supported as described, so that the supporting structure will not have the load concentrated at one side under any condition. Preferably, I desire to supportthe motor from the longitudinal center line of the locomotive structure.

The above and other more detailed objects of my invention are attained by the structure illustrated in the accompanying drawings forming a part of this application and in which:

Figure 1 is a top view of one longitudinal half of the rear end of a locomotive frame worl with a radial trailer truck applied thereto and including a booster motor.

Figure 2 is a side elevation of the same structure.

Figure 3 is a vertical transverse section through one-half of the structure taken substantially on the line 3-3 of Figure 2.

' Figure 4 is a similar section illustrating a modied structure.

Figure 5 is a detail vertical section taken on line 5-5 of Figure 4.

f Figures 6 and 7 are views corresponding to Figures 1 and 2 but illustrating a modification in which the rearward extension of the main frame of the locomotive forms a nonradial truck having pedestals for guiding journal boxes in which the trailer axle is jeurnaled. 1

Figure 8 is a vertical transverse section taken substantially on the line 8--8 of F igure 7.

Figure 9 is a section similar to Figure 8 but illustrating a. modified structure.

In the drawings illustrating the preferred embodiment of my invention, the main frame of the locomotive is indicated at 1 and is shown as provided with a rearward extension or cradle 2 which carries the fire box, ash pan, and cab of the locomotive, which parts are not illustrated as they form no part of my present invention. The rear driver of the locomotive is indicated at 8. A trailer truck frame is pivoted to the locomotive at 5 and is mounted upon a pair of non-driving wheels 6 which support the frame through their axle journals 7, springs 8, hangers 9, and an equalizer' 10. The rear ends of the wheel pieces 4 of the truck frame are connected by a cross rail 11.

A booster is indicated at B and is operatively connected to the truck axle 12 and is partially supported on the latter by means of bearings 13. The rear portion of the motor B projects over the transverse member 11 of the truck frame and is carried on the transverse beam 14 which preferably is rigidly attached to the motor and supports the same from side to side or which, if desired, may form an integral part of the motor frame. This beam 14 is supported at its outer ends by suitable links 15 which in turn are suspended from a transverse equalizer 16 pivoted at 17 to the locomotive main frame extension element 2.

The pivotal connection 17 for equalizer 16 permits the latter to swing in a vertical plane and the pivotal connections between equalizer 16 and links 15 and between the latter and beam 1d permits the links and the beam to swing transversely and longitudinally oit the locomotive. This enables the bootser to shift with the axle 12 irrespective of any correspending movement of the main framing of the locomotive. f

A different pivotal connection between the booster carrying beam and the main frame is indicated in Figures 4 and 5 in which the pivots 18, 19, and 2O have parallel axes to ireely accommodate movement of equalizer 21, links 22 and beam 23 in a plane extending transversely of the locomotive.

In the modification illustrated in Figures 6, 7, and 8, the locomotive cradle 24 also forms a rigid or nonradial truck in which is journaled the axle 25 mounted on the non-driving wheels 26. This axle is adapted to be driven by the booster motor M, which is supported lfrom the rear portion of cradle 24: through a cross equalizer 27 pivoted on the cradle at 28 and pivotally suspending the links 29 which pivotally support the opposite end of a beam 30, carrying the booster motor.

A similar general arrangement with a. different link pivot is illustrated in Figure 9 in ,which the links 30 are pinned to the equalizer 31 and to the cross beam 32, similar to the arrangement shown in Figures l and 5.

In each of the structures shown, the main 'frame element or cradle is provided with a central bracket located approximately on the longitudinal center line of the locomotive and forming the bearing for the equalizer pivot in. p In each of the cross sections I illustrate the booster housing I-I without detailing the mo- 'tor structure and it will be understood that any effective motor construction may b e contained in the housing or mounted upon the motor bed plate I).

With my invention the motor may be carried by supports located at the sides of the motor and the motor may be supported substantially throughout its width. At the same time, the weight of the motor is applied to the training of the locomotive at a central point on the latter. If the frame tilts transversely, there will be less movement oi' the support .'element, relative to the trailer axle, than if the Vsupport element was mounted on the sides of the frame. This also avoids a plurality of connections to the sides of the locomotive framing and permits free movement of the motor support to accommodate the trailer jaxle.
